A 290 -m-wide river has a uniform flow speed of 0.95 m/s through a jungle and toward the east. An explorer wishes to leave a small clearing on the south bank and cross the river in a powerboat that moves at a constant speed of 7.6 m/s with respect to the water There is a clearing on the north bank 64 m upstream from a point directly opposite the clearing on the...
